It all started with a letter and a ring
Flood, at first appearance appears to be a sobbing man, a cascade of tears pouring forth. He is thoroughly soaked. He vaguely smells of rot. As the party confronts or engages him in conversation, it will slowly look like he is melting into his tears. If brought into conversation, he will sound devastated by loss. He will speak of a love gone to sea. After some probing, his sorrow will turn to rage as he blames the party members as representatives of “everyone, all of you with you schemes and your lies. You drove her away from me! You are why she drowned!” at this point he will melt completely into the small lake in the room and thus begin the fight.
When Flood was a true mortal, he and his love lived in Nèra Gomar. Soon, a wide variety of insulting and often absurd rumors began circulating around his love, started by a slighted friend. These rumors spread around the town like wildfire as the young woman was a well-known socialite. Having to face ridicule every time she went outside, she resolved to flee from the city for a while on a ship and would return when she was forgotten. No sooner did her ship leave harbor did a flood tear through the city and her vessel was capsized. Her body was never found. The young man climbed up to the mountain from which the river springs that flooded, killing his love. He planned on throwing himself in to join her.
Once he reached the spring, he was greeted by an old man, weary by countless years. He told the young man that he had only his own wickedness to blame for her death as a human. The young man’s sorrow turned to rage and he picked up a river stone and struck the old man. Again and again, he brought the stone over his head and down of the man who laughed frailly until he was silent. The spring ran red with blood and the young man tried to drown himself, for his grief and his horror at his sin. He found he was incapable. no matter how hard he tried, how much water he breathed, he was incapable of drowning, so he stayed and wept. Over the years he came to blame the wickedness of people who drove his love to sea to begin with. Human kind is envious, petty, and cruel and deserves to drown as she did.
